How to change the circular saw blade
Supplies you will need
- A new circular saw blade
- 13 mm wrench
- Measuring tape
Tools you will need
- A cordless circular saw
- Safety gloves
Steps to Change the Circular Saw Blade
Step 1: Disconnect the Power
In the first step, you need to make sure that power is disconnected. You can do this by unplugging the circular saw from the outlet or simply removing the battery from the Black and Decker cordless saw.
Step 2: Removal of the Blade
To remove the blade, you have to press the blade lock. Use the blade range to turn the blade until it stops rotating. Keep going in the clockwise motion and continue pressing the blade lock to loosen the screw.
You have to remove the following three things:
- The screw
- The washer
- The old blade
Step 3: Removal of Dust
Before you move on to the final step of replacing the blade, you have to remove any sawdust collected in the blade guard. Once the sawdust is removed and everything is neat and clean, you are good to go.
Step 4: Finding the Indicator
Find an arrow mark that is printed or engraved on the saw blade.
Almost all the saw blades have this arrow mark on them. This is an indicator of the way the blade should be installed in the saw.
Make sure that the teeth point towards the front of the saw. If you do not find it anywhere at all, you need to make sure that the teeth are facing towards the front of the saw.
Step 5: Replacing the Blade
In this step, you will place the blade on the arbor. You have to ensure that the teeth point towards the front and replace the washer and the screw.
After this step, you have to press the blade lock and then use the blade and turn it until the blade stops turning. Keep going in a counterclockwise direction with a wrench to tighten the screw further.
How to determine that your circular saw needs a blade change?
It can be difficult to tell when you need to change the blade of your cordless circular saw. But some factors determine that it is the right time to change the blade of yourself. Let’s have a look at them below.
Area Around the Blade
You can determine that you need to change it when you notice the wall area around the blade is significantly worn out.
Sound of the Saw
The next factor is the sound of the saw. If it sounds like it is struggling too much to cut lumber and the motor of the saw is making a lot of noise, we’re pretty sure that the blade has started to dull.
Fighting Blade through Lumber
If you feel like the blade is fighting too much to pass through lumber, you should know that it is the right time to change the blade because it is not supposed to struggle.
Not that the blade is supposed to cut through thick wood pieces like butter.
Wrench Size
A wrench plays an essential role in changing the blade of your cordless circular saw. The wrench comes in the carrying case box with your circular saw.
Try not to lose your saw’s original wrench, it could be difficult to find a perfect fit later.
Usage of the Wrench
The trick in using the wrench properly is locating the little brake mechanism on the circular saw. This will ensure that the blade is locked in one place and does not spin while you are trying to remove the blade.
Push Down the Silver Tab
Push down on the silver tab inside the circular saw. You will hear that it snapped into place and is locked. Put the wrench on the bolt of the circular saw blade and pry back gently.
This process does not require a lot of force at all. If you have lost the wrench, you can purchase a 13 mm one from any hardware store near you.
Choosing the New Saw Blade
Choosing the new circular saw blade for your circular saw is a crucial step. Let’s take a look at the things you need to keep in mind before changing the old saw blade.
Diameter of the blade
First of all, you should check the diameter and size of the blade before you try to replace it.
This should be printed on the circular saw. In case it is not printed, then you will have to measure the blade size and diameter.
Once you’re done with the previous step, measure from side to side through the center of the blade. Use this measurement to purchase a new circular saw blade for your cordless saw.
Arbor diameter
Checking the arbor diameter is also necessary before you replace the old circular saw blade with the new one in your saw.
Make sure that the hole in the center of the Blade fits perfectly on the shape of the arbor in the circular saw.
If you don’t know the arbor diameter, you can take it to a home improvement store to ensure that your new blade is a perfect fit.
RPM
Check this before replacing your old circular saw blade. Make sure that the maximum RPM rating of the new saw blade is not exceeding the RPM rating of the circular saw.
Wrapping it up…
The blade of a cordless circular saw becomes dull over time. This is inevitable so you should not worry about it too much.
We have researched and brought you a detailed method of changing the circular saw blade, which means you do not have to visit an expert.
Once you have changed the circular saw blade, you are good to go.
